head gaskets

On a mild build, gasket sealing shouldn't be an issue.
depending on chamber volume, I'd go for the thinnest gaskets you can find. (Thinnest off the shelf that is) The 302 heads have the squish pad, so a nice thin gasket will aid the pad in generating that peak pressure turbulence which is the main draw card of the 302 heads.
I'm sure people who know more than me will chime in to recommend a specific gasket/part number etc.
